And a light combining and condensing unit that collects light using a predetermined condensing lens and obtains condensed emitted light after combining, and the projection unit modulates the condensed emitted light based on information of an input signal to the optical modulation unit, the light from the front Symbol light modulator and a projection optical unit for projecting the image on a predetermined screen, the light source unit and the projection unit are separated and bondable configured together, the The light source unit and the projection unit are aligned so that the optical axis of the predetermined condensing lens and the optical axis for incident light set in the projection unit are coaxial when coupled to each other. Possible, Source unit and for alignment mechanism for a projection unit each contain.
この発明に係る請求項４記載の投写型表示装置は、光源ユニット及び投写ユニットを備える投写型表示装置であって、前記光源ユニットは、複数の固体光源と、前記複数の固体光源からの光を合成して合成出射光を得る光合成部とを含み、前記投写ユニットは、前記合成出射光を所定の集光用レンズによって集光する光集光部と、前記光集光部から受ける光に対し、入力信号の情報に基づき変調する光変調部と、前記光変調部からの光を所定のスクリーン上に映像として投写する投写光学部とを含み、前記光源ユニットと前記投写ユニットは互いに分離・結合可能に構成されている。 According to a fourth aspect of the present invention, there is provided a projection display device comprising a light source unit and a projection unit, wherein the light source unit receives a plurality of solid light sources and light from the plurality of solid light sources. A light combining unit that combines to obtain combined output light, and the projection unit collects the combined output light with a predetermined condensing lens and receives light from the light condensing unit. a light modulator modulating based on the information of the input signal, the light from the front Symbol light modulator and a projection optical unit for projecting the image on a predetermined screen, the projection unit and the light source unit separated from each other, It is configured to be connectable.
ＤＭＤチップ２５では、図示しない入力信号に応じてマイクロミラーの傾きが変わり、光がＯＮ光とＯＦＦ光に変調され、ＯＮ光のみが投写レンズ部２６を介して、スクリーン３０上に映像として投写される。 In the DMD chip 25, the tilt of the micromirror changes according to an input signal (not shown), the light is modulated into ON light and OFF light, and only the ON light is projected as an image on the screen 30 via the projection lens unit 26. The

図９及び図１０に示すように、ＬＥＤ光源ユニット４０は、実施の形態１のＬＥＤ光源ユニット１０と同様、３つの固定光源であるＬＥＤ１１（赤ＬＥＤ１１Ｒ，緑ＬＥＤ１１Ｇ，及び青ＬＥＤ１１Ｂ）、３つのＬＥＤ１１に対応した３つのコリメータレンズ１２（コリメータレンズ１２Ｒ，１２Ｇ及び１２Ｂ）、赤反射ダイクロイックミラー１３、及び青反射ダイクロイックミラー１４を内部に有している。これらＬＥＤ１１、コリメータレンズ１２、赤反射ダイクロイックミラー１３及び青反射ダイクロイックミラー１４はＬＥＤ光源ユニット４０内の所定箇所に固定される。 As shown in FIGS. 9 and 10, the LED light source unit 40 is similar to the LED light source unit 10 of Embodiment 1 in that three fixed light sources are LEDs 11 (red LED 11R, green LED 11G, and blue LED 11B) , and three LEDs 11. 3 collimator lenses 12 (collimator lenses 12R, 12G, and 12B), a red reflecting dichroic mirror 13, and a blue reflecting dichroic mirror 14 are included therein. These LED 11, collimator lens 12, red reflecting dichroic mirror 13, and blue reflecting dichroic mirror 14 are fixed at predetermined positions in the LED light source unit 40.
ＤＭＤチップ２５では、図示しない入力信号に応じてマイクロミラーの傾きが変わり、光がＯＮ光とＯＦＦ光に変調され、ＯＮ光のみが投写レンズ部２６を介して、スクリーン３０上の映像として投写される。 In the DMD chip 25, the inclination of the micromirror changes according to an input signal (not shown), the light is modulated into ON light and OFF light, and only the ON light is projected as an image on the screen 30 via the projection lens unit 26. The
（その他）
なお、実施の形態２においても光源にレーザー等の固体光源を使用しても同様の効果が得られる。また、光源の合成にミラー順次式を使用しても良い。また、光変調部であるライトバルブに液晶パネルを使用しても良い。つまり、実施の形態１と同様の変形が可能である。
(Other)
In the second embodiment, the same effect can be obtained even when a solid light source such as a laser is used as the light source. Further, a mirror sequential type may be used for combining light sources. In addition, a liquid crystal panel may be used for a light valve that is a light modulator . That is, the same modification as in the first embodiment is possible.
